I know we already heard that the wheatley kernel wasn't intended for the nexus s 4g, but I just wanted to report that when using it with bluetooth playing audio I get stuttering like the CPU is too slow to play the mp3. When I switch back to other governors like lulza or lazy it doesn't happen... tried with and without deep idle. Using deadline scheduler on cm9. also had a reboot this morning at stock voltages fwiw. Thanks for the great kernel work!

Edit. I forgot to mention that I did try playing audio through headphone jack with voodoo audio and I didn't have the same problem on wheatley.

Quick question. Ezekeel claims that Wheatley was never intended for the NS4G and that it would cause problems if used. However, I have been using it for a few days now and it has been running wonderfully. In your knowledge of kernels, governors, etc. can you tell me what it is about the Wheatley gov that would make it potentially hazardous to use on the NS4G?
[Nexus S 4G Android Development] SA-07:
Technically it doesn't have that C4 idle state, so it's basically an ondemand...

But ezekeel told me it will cause excessive screen on battery drain which is weird considering it is giving good results.

I don't see it as potentially harmful though...
[Nexus S 4G Android Development] mlin:
Back in the day some ROM builders recommended turning off wifi and data while flashing ROMs on WinMo phones...
[Nexus S 4G Android Development] the1dynasty:
my phone just physically exploded, like BOOOOOM, running "Wheatley"

j/k... if there's cause for concern running wheatley, i think it's just superficial b/c it runs great on my phone...

---------- Post added at 11:24 PM ---------- Previous post was at 11:20 PM ----------

i have noticed huge gains on idle and definitely some quicker battery drain with the screen on... this sounds plausible... maybe someone can take a look at it and adjust the screen settings while on??

*hint hint* ;)
[Nexus S 4G Android Development] mushupork:
Here's my assessment of the Wheatley governor. Screenshots below.

In battery usage, it is obvious that there is significant battery loss when the screen is on and the phone is in use (think "performance" governor :eek:). However, battery use when screen is off is lower than with any other governor I've seen. My phone will literally lose only 0 or 1% battery over 3 hours of sitting with screen off.

I can see a value use case for this governor, however. Depending on how you use your phone, the battery saving during screen-off may offset the battery use during screen-on, particularly if you have long periods of little or no use.

My settings are 100/1000, no OC, default voltage, deadline scheduler all set through NSTools. I'm going to charge to full tonight and try lulzactive with deadline, then do the same with smartassv2. Note, I only care about performance in terms of lag-free UI. I am far more interested in battery life.
[Nexus S 4G Android Development] the1dynasty:
thanks for confirming what i said in the thread on kernals... i noticed today that my phone was off the charger for over 1hr before dropping from 100% to 99% and the same from 99 to 98... when not in use, it's amazing standby time!!
[Nexus S 4G Android Development] mushupork:
I second that emotion!

I think wheatley could be *the* killer governor for battery saving if the code could be tweaked to prefer lower frequencies while screen on. I know this somewhat goes against the "race to idle" argument, but it seems like it could work.

I'm thinking a bastard love-child of smartassv2, lulzactivev2, and wheatley. Let the governor menage a trois begin!
[Nexus S 4G Android Development] Skunk Ape1:
I agree with this 100%. I have seen the same results on my phone. Much better battery savings when the screen is off and more loss when screen is on.

in 18-23 hours I only have screen on for around 5 hrs. This is about the same as I get with the lazy gov. with all other settings the same. The difference is the speed of the phone is better with the Wheatley than the lazy. I'll take that every time.

MathKid, can you please tell me why my phone turns off when my battery is less than 3%? its not dead yet, i have to do a battery pull to get it back on or to even see that its charging. This happened two nights in a row, dies when the battery is almost dead but the phone doest wake up or charge, so sleep of death I guess?
[Nexus S 4G Android Development] the1dynasty:
did you calibrate your battery? it could be showing that % but might actually be lower?? just throwing suggestions!
[Nexus S 4G Android Development] RushAOZ:
Me too. When the thing is is off sitting on my bed the battery drains... but nowhere near as fast is does when its awake and in use. Once again I blame this on the radio. When we get ota well get the radio ics wants. No matter what rom kernel combo I try my battery life is a lot worse than gb cm7 running at 1.4 ghz.
[Nexus S 4G Android Development] FL0OD:
It's probably because this has a cosmetic charge that shows your phone charging to 100% when it's really only at 96% so when it gets down that low its really at 0% but we wouldn't know that because it shows a artificial number. I'm just guessing.

[Nexus S 4G Android Development] oxeneers:
I'm very happy with the idle state of the Wheatley governor, which yes, offers huge battery savings when idle. The screen on drain is pretty big, but I think it's worth it since I'm not able to check my phone when I'm at work usually, only on my breaks. So it works for me.
[Nexus S 4G Android Development] FL0OD:
Can anyone show me what high battery drain is on Wheatley with the screen on with a screen shot just so I can get a glimpse of what everyone is speaking of, or those of you experiencing it? Thanks.

[Nexus S 4G Android Development] FL0OD:
What's your onscreen time like? That seems to be what I saw people talking about was the Wheatley kernel and the bad onscreen battery drain.

°•neXus S4G•°
[Nexus S 4G Android Development] Skunk Ape1:
before the Wheatley I've been using the lazy gov, 800 max, 200 min. Deep idle on, noop scheduler. and was getting 18-24 hours with 4-5.5 hours screen time.

With the Wheatley gov and no other changes made, I'm getting the same 18-24 hours with the same 4-5.5 hours screen time.

The difference is overnight I drop from 100% down to about 93% with the lazy gov and drop from 100% to only 98% with the Wheatley gov. My day long average however remains the same with both. Since my average battery life remains the same and my sleep time improves, my conclusion is my screen on time uses a little more than it did with the lazy.

Also my phone is more responsive and smooth with the Wheatley gov. I constantly get higher quadrant scores with the Wheatley gov than the lazy gov. Normally by 200-400 points higher.

My screen time of course is broken up throughout the day.

To me its really all about the kernel unless the rom is just garbage. This is my screen on time from a ROM I am testing for some one. Lazy governor, stock voltages. Kid has just hit thing out of the park.

°•neXus S4G•°
[Nexus S 4G Android Development] mushupork:
My onscreen time was 2hr 7min. A fair bit of that onscreen time was spent playing Monopoly, which is fairly processor intensive.
[Nexus S 4G Android Development] Skunk Ape1:
I never really stated it was bad, but not as good as the lazy. What it loses to lazy in screen on time it makes up for it when sleeping. Again by the end of the day both the hours on charge and my screen on time are about equal with both. It's just the performance is better with the Wheatley.

[Nexus S 4G Android Development] mlin:
How long did the battery last? I don't take much from your screen shot simply because I could set my phone to never sleep, leave it alone and have the screen stay on for 4+ hours with most any kernel. Seeing how long your battery lasted and what else you did with your phone gives a more complete understanding of whether or not your screen shot is something to be impressed by.

[Nexus S 4G Android Development] crzycrkr:
I'm on AOKP21 and its rock solid stable for me. No problems whatsoever. Haven't tried Codename. Came from oICS43 to try out some of the newer features.

[Nexus S 4G Android Development] the1dynasty:
with nearly 2000 posts in this thread, i don't blame anyone for not reading all of the posts... maybe that could be posted in the OP?? i haven't looked so idk if it's even there lol :D

just a suggestion!!

btw, been running 1460MHz and with about 1hr of screen-on time, i'm over 12hrs right now with 63% left... strange thing i've noticed is that when you heavily use the phone with these settings (noop+wheatley), the battery will drop rapidly, but the moment you stop and let your phone idle, it actually flatlines and in some cases the charge goes back up by itself... weird, i know...
[Nexus S 4G Android Development] SA-07:
Ok! I will just put it in the FAQ... sorry bout that
[Nexus S 4G Android Development] wctom:
I would take all battery-meter readings with huge grains of salt. On multiple ROM's and kernels, I have noticed that at around 20% charge, the graph line takes a huge dip towards zero. That would indicate to me that the previous 80% is just a cartoon.

The actual time from full charge to dead phone would be a better indicator of battery life.
[Nexus S 4G Android Development] SA-07:
Yeah, there was a discussion where it was said that there was some base charge, kind of like a calibration (a better term would be a zero mark, but it's not really 0) where the number shown on the battery is actually the difference between that and the "zero" mark. So the number shown on your battery isn't really true...

I haven't really investigated this but it was just put out there
[Nexus S 4G Android Development] Saneless:
I've had some battery issues with v15 and deep idle rubbing apex, 14.5 seems to be working well though.
[Nexus S 4G Android Development] SA-07:
What issues exactly? What governor?
[Nexus S 4G Android Development] wctom:
Yeah, that makes sense. The calibration marks seem to be "full-charged" and "20% charged". If you look at all the posted battery-curve pics, every one of them show a sharp dropoff at around 20% (maybe 15%). In my opinion, that makes all claims based on battery-meter readings worthless.
[Nexus S 4G Android Development] SA-07:
That's interesting... can someone else post their battery graph to confirm this?
[Nexus S 4G Android Development] Skunk Ape1:
I've had absolutely no issues with either one of them but prefer codename Android only because it ha most of its tweaks in the settings menu.

Lulzactive, and was getting no top off values for deep idle, I would lose about 10% of my battery in half a hour.
[Nexus S 4G Android Development] Skunk Ape1:
Ok... I misunderstood what you were wanting Mathkid. My phone is now @ 7% While the portrait view looks like it dropped really fast after hitting 20%, in the landscape view it doesn't look as drastic a dropoff. So it may just be an illusion because of the screen restraints while in the portrait view.

Hell yeah! over 22 hours and almost 6 hours screen time and still going. I am loving v15!!!!!!
[Nexus S 4G Android Development] the1dynasty:
now i've been home all day today and haven't really used my phone much with just about 1.5hrs of on screen time... i'm over 17hrs with 55% left... current settings are 100/1460MHz and of course noop/wheatley...

What are your settings and habits.

I have facebook (frozen), I also froze sprint hidden menu, drm protected content, wallet and tags. All of these are known battery killers. Monday thru Friday (during work), I disable data as I'm not allowed to answer or pickup my phone or use it in any way. During my 2 15 minute breaks and my 30 minute lunch, I turn the data back on to check my mail and read my forums.

I generally make up for my down time at work when I get off. Even with my downtime at work I still get at least 4 hours screen time a day. Usually closer to 5.

Your kernels are really exceptional. I guess you could throw in some more governors so we have more capacity to experiment.

[Nexus S 4G Android Development] enosh816:
I am using codename and was wondering how you are getting the cpu settings to stick after reboot. My gov keeps changing to lazy when I reboot. Also are you still using nstools. I thought I would ask you becouse I keep following your settings and You seem to know your stuff alittle more than your average Joe. And to give another shout to mathkid. Your kernels are outstanding.

Just FYI

I noticed your icons for your battery and wifi are from that awesome theme, cant think of name offhand. I liked the circle battery better so after I pushed shanes theme I pushed the bat mod that codename has and I still have shanes theme but with the cir bat mod. Just fyi incase you didnt know you could do that. I also wanted to share that after I switched from a o s p rom I did an advanced restore and only restored data and all my apps and settings restored and there doesnt seem to be any side effects also fyi. I am just trying to give some info that might help when swithing mods. My way of trying to return the fav. for all the helpfull advice that you have been sharing.
[Nexus S 4G Android Development] Skunk Ape1:
First of all thanks for the props.

Go to the system settings, codenamed settings, performance settings and make sure set at boot is checked

Nstools... On top you should see tabs. The right most tab is settings. Make sure "Set at Boot" is checked.

Make sure it is checked in both places. If you don't have nstools installed, just checking it in settings should work. No need to install nstools if you haven't already done so.

MK, this is your "under 20%" stats (photo taken at 9% remaining b/c i don't feel like waiting til it dies all the way lol)...

this is NOT a normal amount of use...

data was off on flatline.

just over 3hrs of screen-on time.

about 1-2hrs of streaming music via Pandora.

less than 20mins/talk time.

most of the screen time was from texting.

add about 6hrs of "airplane mode" while i slept (battery didn't even drop 1% during this time).

as for the "dropping faster under 20% theory" i don't buy it... look at my graph, yellow starts at 25%... but look where it started to drop, i streamed music while driving home from work that entire time... when i got home, that went off and it flatlines again... my phone was still sitting at 10% for over 1hr... if that theory is valid, then my phone disagrees!! :D
[Nexus S 4G Android Development] chalan30:

The tweaked conservative gov you put in v15.5: Is that the same one from franco?

If so, reading his thread it looks like he just tweaked it to act exactly like min/max gov. I.E. - bounce between min and max freq without using any intervening freq steps.

Not making any pro/con comment, just curious. :)
